Fig. 7

Precipitate in the simulation domain for the crystalline anisotropy is reflected in the left column, for the classical model, and in the right column, for the natural model. In the top row, the initial setup (\(t=0\)) is shown as a red dashed line, and an intermediate state (\(t=30\)) is shown with black solid and dashed lines, corresponding to the loci of \(\phi =0.5\), \(\phi =0.01,\) and \(\phi =0.99\), respectively. In the bottom row, the final (\(t=600\)) results (black lines) are overlapped by the corresponding Wulff shapes (magenta lines), due to the appropriate surface energy plots (blue lines)
